I have install hdp 1.3.1 using ambari, and deploy the correct topology script. I can see the rack information when namenode and job tracker startup. I can also see the rack information by running “hadoop fsck /” in which “Number of Racks” is displayed at last.

But the “heatmaps” in the ambari web always show as “default rack”. Does anyone else also encounter the same problem? Is this a bug?
